-CoQKING-s'rov.

A The 'S-chedule referred to in these Letters Patent and making part of the same.

To all whom litmag/ concern:

Be it known that I, Grt-:onen WnLLnoUsn, of Akron, in the county of Summit, and State of Ohio, have inventedl certain'new and useful Improvements in Stoves; and I do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, making part of this specification, in which-.

Figure l is a side view of the stove.

Figure 2, a transverse section.

Figure 3, a view of the top.

VFigure 4, a longitudinal section.

Figure 5, a detached section.

Like letters of reference refer to like parts in the views presented. l y

'lhe nature of this invention relates to the coust-ruc--- tion and arrangement of the ues of a stove, whereby all, or nearly all, ofthe bottom and back of the oven is exposed to the heat ofthe fire in its direct draught, thereby increasing the heating-capacity of the stove in relation to the oven, and furthermore, retaining and reintbrcing the heat of the walls of the flue by the return draught.v

This invention also relates to the lire-grate, which, by giving to Aita combined reciprocating,.oscilla-ting, and-revolving movement, theashcs can be more speed! ily and thoroughly shaken from the fire-box than can be done in the ordinary way.

In iig. l, A represents the outside of the stove, B' the fire-place, and 0,'tl1e oven. AnY inside View of the tire-place, from the top, is shown in iig. 3, thcfront, section of thestove, immediately over theiire, being represented as removed, in order that the inside may be seen.

D, iig. 2, are the side-fines, a side view of which is indicated by the space enclosed lby the dotted line a., tig. l.

These ues, as will be seen in iig. 2, are of a trian.. guiar shape, and are formed `by the plates E F, the lower edges of which are based against the bottom of the stove at b.

The upper edges approximate and abut against a rib, e, extending lengthwise the stove, forming au arch-like roof to the central return-flue These horizontal 'lues D G have their corresponding vertical tlues D G at the rear end of the stove, as seen in iig.-3, the rear walls of ucs D' being indicated by the dotted lines C', and which, as will be observed, are ofA a triangular cha lact r, similar to the horizontal side ones above described, and are constructed inthe same way, viz, by a pair of plates, indicated by the dotted line C', arranged at an angle to the back oft-he oven. p

The inner edges of said plates meet atthe centre of the transverse diameter of the oven at c, against a rib, indicatedl by the vdotted Aline 1v, -iig. 2, and recede backward and outward ucar tothe sides of the stove, as indicated by the dotted lines referred to, brlning an arch similar to that described of the horizontal iiue.

'lh'c rear walls of the vcrticalftlues 1) also form the front wall of the cent-ral iiue'G, iig. 4, which shows a longitudinal vertical section of the stove. l

l, figs. 3 and 4, is a `partitioli-plate, arranged at au angle between the top of the iues and the top of the stove, dividing the area above the ues and oven transversely, and in suchrelation to the fues that the corner ones, D', are in front on the one side ofthe plato, and the central ue G on the other.

Said plate is provided with draught-openings E', ex`` closed, for a purposehereinafter shown'.4

Having thus described the construction and arrangement of the lilies, the practical operation of the samev isas follow The damper I/ being closed, as shown in tig. 4, the heat and smoke fromv the tire-box flow back over the ftop of the oven, as indicated by the arrows .iu lig. 5, descend the vertical corner-lines D", thence along the horizontal i'lues D to the front, as indicated bythe arrows in fig. l; then returning under the oven through the central flue G to the vertical flue G', and from :thence to the stove-pipe J. It will be obvious from this that theI vertical lines 1) and Gare continuations of iues I) G.

This arrangement of the iiues for direct and .return draughtsl do not claim, but that which distinguishes my invention from others is the shape of the fines, and their special'construction by means of plates.

Flues as now used are of a somewhat square shape, and cast ent-ire, the capacity of the side`-flucs being about one-half of theJ surface of the oven, around which they run, and the centre flue about one-half.

In consequence of the square shape of the flues, the hea-t, in its way around from the fire-place to the front, is not distributed evenly over the entire surfaceof the back and bottom of the-oven, it being confined to the lues which cover about onefhalf the surface at .the sides, the' other half being covered by the return-flue, therefore the oven'is unequally heated, the sides immediately covered by the sideiiues becoming much hotter than the central part covered by the central ue, which is heated only by the return draught.

This unequal heating ofthe oven not only interferes with the process of baking, which cannot be uniformly vdone, but in consequence of the unequal expansion of the plates, occasioned by the unequal heat to which they are exposed, they warp and often crack, thereby seriously injuring the stove.

I am also aware that a single at plate has been interposed between the bottom of the oven and the 4 bottom ofthe stove, thereby dividing -the space below tion to the draught.

In order to avoid these evils, I construct the ilues of two plates, E F, above referred to, which, by arranging them at ariangle, as 'shown in iig. 2, viz, bringing the two upper edges together against the rib, forming an arch-like root' to the middle flue G, it will be obviousvthat larger ordeeper ilues are obtained than those made by the interposition of a tlat plate, and at the same time exposing all, or nearly all, the 'entire surface of the bottom and end of the oven to the for# ward draught, thereby distributing. the heat, so that the oven will be uniformly heated and in much shorter time, also with less consumption of fuel than can be done by the square lines; also, by this shape of the tlues, greater depth is given them than those constructed of a plate. They are less liable to ll up by the deposit of soot and ashes, and, when t-hus choked up, are cleaned out with less trouble, and more expeditiously, vin consequence of their greaterdep'th. Also, the plate referred to, in consequence of its larger size, is liable to warp and crack, and thereby do serious injury to the stove, whereas lues constr`ucted of two plates, and arranged as above described, lare much less liable to this defect, hence'will be more durable and less expensive to replace when required; also the rib against which the plates abut add to the strength of the bottom of the oven.

On v.dropping the damper I', as indicated by the dotted line j, Iig. 4, shown also in iig. 3, a direct l' draught is obtained, thereby allowing the heatand smoke to pass immediately to the pipe, instead obeing compelled to pass down and around the oven through the lines, as above described.

A further improvement consists in the peculiar construction ofthe lire-grate K, which consists of a frame, L, hung upon trunnions or shafts M, wherebyis ob tained to it al revolving and reciprocating longitudinal movement.

In said frame are the bars N, which are pivoted in the sides ofthe frame, at the points t, iig. 5, the horizontal bars being rigidly attached to the pivots.

lo the under side of the bars are attached, in a rigid manner, a pair of semicircular plates, O, fig. 4, the

edges of which are heldin a groove, as shown in fig. 2, in which they play, on a revolving motion being given tothe frame, and at the same time gives -to the bars an oscillating movement when the frame is made to move in a longitudinal direction.

Thus, on pushing the frame in the direction of the arrow, igj, the bars will be made to assume the po-Y sition indicated in the appended Fig. X, in consequence of the edge of the circular plates being retained in the grooves while the bars move forward. i Now, on reversing the movement of the frame, the bars will thereby change their position to that indicated by the dotted lines a', and so on, as the Vframe may be continued to be shaken backward and forward, the bars correspondingly change their position.

By ,this combination of movements, viz, the recipro. eating and revolving movement of the entire grate, and the oscillating movement of the bars, the ashes can be easily and thoroughly shaken from the replace, and the whole contents thereof can be deposited in the ash-pit by turning the grate to a vertical position, as indicated by the dotted lines n, g. 4.

At the rear end of the stove lare hinged'a pair of shelves, l? P'. These shelves are for the convenience of placing articles thereon needing to be kept warm, or other articles required to be placed out of the way. 'ihese shelves, being hinged -to the stove, can bev turned 11p out of the way when not in use, as shown bythe lower one P.

Said shelves are retained in a horizontal position by the checkblocks S, against which the inner edge of the .shelf strikes,`as shown at P, the upper shelf.

What I claim as my improvement, and desire to secure by Letters Patent, is-

' 1. The plates EF, as arranged in relation to each combination with the rib-c, side-fines DD, and oven O, substantially as and for the purpose set forth.

2. The plateI, as arranged in relation to the ilues D and G', in' combination with the damper I', for the purpose speciliedl 3. The oscillating bars N, semieircular plates O, in combination with the shaft M and 'frame L, in the manner substantially as and for the purpose described.

4. The shelves P1P', as arranged, in combination with the stove A, for the purpose specified. GEO. WELLHOUSE.
